The invention relates to machines for scoring ice cakes such as aredelivered from the freezing cans in an artificial ice plant so astopermit of subsequently dividing the cakes into sections of exactlypredetermined size i and Weight.

In the present state of the art various inachines andmethods have beendevised for accomplishing the scoring of the caire, but all Y haveinvolved more or less complexity, which has interfered with theconvenient handling of the ice and has increased the labor thereof. Itis therefore the obj ect of the present invention to obtain a`construction of machine '15 Which may be conveniently installed in anori such a cake is in motion, it is difficult tostop the same Withouteither overcarrying the mark or causing a rebound. The cake mustnecessarily be accurately positioned With relation to the scoring saws,which, on account In my iinproved construction provision is made forallowing the ice cake to move beyondk its position of registration undert-lie'yielding resistance of a buffer and for then returning the T Vcaketo a fixed stop, which accurately positions the same. Y

Still another object of the invention is to simplify the mechanism andstructure of the machine and to economize space occupied 4=0thereby. Y

Generally described, my improved machine comprises intermittentlyactuated means for successively advancing the ice cakes through arectilinear course, a frame` through .Which the cakes passv and in Whichthey dwell for an interval, and scoring devicesoperated during theinterval of rest of the cakewithinV the frame and transverselytraversing the saine on opposite sides and in opposite directions.y Thisavoids .the necessity of returning the scoring devices after ythecompletion of a transverse cut, aslsuccessive cakes may be scored bymovements in opposite directions. The longitudinal scoring of the cakeis effected during the move- `ment into the framev and the completelyscored cake is delivered from the frame by a Thus the frame, anintermittent feed mechanism, scoring devices in fixed position on Vsaidframe for operating on the cake While advancing,

.and scoring. devices. on opposite sides of the frame intermittentlytransversely movable thereon in opposite directions.

- Frame and rear upright frame members 1 andr2 each 25 flanges.

having spaced sides for the passage of the ice cake therebetween. SeeFigs. 1, 2 and 4. At the topY of the front frame is a transverse framemember 1a on which is mounted a y 5 motor 3 for driving the operatingmechanism.. The frames 1l anda2-are connectedzto each other byllongitudin'ally entend-ing tie members 4 near the base and a tierod. 5at the top, thereby forminga substantially rec- `tangular structure of alength somewhat greater than the length of the'i'ce cake to` be scored.

Feed mechanism Centrally of the frame and at the base thereof are'arranged spaced? parallel guides `6 for receiving a.reciprocating'slideV bar 7. See Figs; 1, PTand" 8. s'sl'iown, theslidebar .7 is formed of a pair of angle bars'7, 7b,

spa'ced fromeach other andi havingouti of passingbeneath the ice cake-Beneaththe barl 7 there is arrangedianrendless feedfchain 1O` whichxpasses aboutsprockets. 1'1 and 12 journaled respectively near the frontand rear of the main frame. The chai-'n 10: has

connected thereto theY dog 13 adapted" to alternativ l engage with'bea'nUslfa'n'd 15 e y i n b -trallyofthef rear: frame 2v and near-the top--on an arm 16 depending from the forward 'end' Qf'thexba'r 7. Thearrangement is such that` the' dog 1'3 while travelling along' the 4Uupper course of` the chain willE engage the bearing.` 14 and" feedVl thebar 7v forward until such 'bearing passes. beyond; the sprocket' 12. Thedog thenv disengages fronrthe bearin'g'f but engages with the lowerbearing 15'which i5 feeds thebar rearward until' saidbearing 1'5passesbeyond the sprocket 11'. See'ligs; 7 and215. Thus a reciprocator'ymovement is imparted to the bar 7, which, as hereinafter set forth. willfeedan ice cake from. a posi- 'ti'on infront of the'frame into the spacewithin the frame andv will simultaneously feed1 the scored ice cake'which ris within the frameioutward from the rear end thereof` 5 "Icecans for the. manufacture -of artificial ice usually taper slightly fromtop to bottom to 'facilitate the withdrawal of the. frozen cake.This-formsa cake withnon-parallel sides, and consequently, a: linerparallel to either Sider will not'y divide thecakeinto. equalThis-elevating means; isJ automatically operated by the feed dog 9 andis preferably constructed as follows:

17 is a supporting bearing upon a link 18 which is pivotally connectedat one end to the flight 9 and at its opposite end is provided with a;cam slot 19 through which4 a transver-se pin-2O passes. See Figs. 7 and15. The pin. 20 passes through the angle bars 7 a, 7", and forms abearing over which the cam rides so that the swinging of the flight 9from horizontal to verticalv position will cause the upward travel ofthe bearing 17 until it is elevated the proper' amount for supportingthe small end.v of the ice cake; A spring 21 yieldingly actuates theflight 9 towards uprightposition, but permits ofthe depression of saidflight'inf the rearv movement of thebar 7 so that it may pass beneath aniceoa'ke.. The icecake issupported upon any suitable platform in frontofthe frame ofthe machine,y

which platform is slotted for the passagev of the bar' 7 and isprovided? with extensions of the guidesk 6\ for supporting saidf bar.The forward flight 8 is similar in. construction to the flight 9 withtheomission of the link 18.

have provided for by a\ yieldable stop- 22 (,Figs..2;.6,.1=5 and-'16),which islocated centhereof and isconnected to a .draft rod 23havspring'24e (Figrl) for nesistingfmovementthereof. Pivotally securedtothe front frame 1 is the; gravity dog-25 which is yieldabliy supportedbythe link 2'5ai having the spni'ng2`5vb sleeved thereon and engaging anabutmenton-vthe-frame. rllhe dog 25 has an inclined portion (Fig. 15)-Which is in the path ofthe upper portion: of the ice cake and by whichit is lifted. At the forward end of this dog is a stop 26V whiclr, afterthe passage of the cake, will drop in rea-r thereof and limit the`lreturn movement of the cake. rI-hus when the cake strikes theyieldable-stop- 22, said stop'` will be carried forwardJ unti-l themomentufmfis absorbed by thespringQl.. The spriing willthen draw theAstop '22' and ice'ca'ke backward until. the stop 26 prevents furthermovement. In'this position the: ice cake is properly registeredv for thetransverse scoring operation. Inasmuch, however, asicecakes are not allof the sameY dimensions, further provision is made for' adjusting thenormal posi-.tion of the stop 22 which consists in a clamp22a-adjustablysecured: by tliefclamping bolt 22b upon the rod 23; Arsv the stopl 22would interfere withy the outward feeding of the ice cake by the dog 8after the Vscoring i scored on ling arm connected to a rod 28, which atits opposit-e end is connected toa rock arm 29 on a vertical rock shaft29a" having a rock arm 29b at its base. The rock arm 29b extends intothe Apath of a lug 15a on the bearing15 which is so lpositioned that inthe final rearward movement of said lug, it will actuateV the rock armv29b (as indicated in dotted lines in Fig. l5)

andthrough the intermediate mechanism lift the latch. 27 and release thestop 22 just in ad- -vance of the forward movement of the feed 'bar 7.This will permit the'flight 8 to feed out the ice cake withoutinterference from the stop 22 and as soon as the rear end of the cakehas passed the stop 22, the latter will fall and automatically re-engagewith the latch 27.

' Longitudinal scoring means The longitudinal scoring of the oppositesides of the ice cake is effected by a pair of horizontally arrangedsaws which are positioned in the front frame 1 upon opposite sides ofthe path of the ice cake. These scoring saws 30 (Fig. 2) are mountedupon vertically extending arbors 31 which are journaled in' bearings 32and 33 in the frame l. The arbors are constantly driven by a gearhereinafter described, and therefore, while the ice cake is being fedinto the frame by the Hight 9, it will be centrally longitudinallyopposite sides thereof by the saws 30. i A

Trams/verse scoring means On opposite sides of the frame are arrangedhorizontally extending arbors 34, on each of which are adjustablymounted a plurality of saws 35.v See Figs. l, 4 and 11. The arbors 34are journaled at theirk opposite ends in bearings 36 in-verticallymovable slides 37 and 38, which latter are mounted on vertical guiderods 39 (Fig. 6) fixedly positioned in the frame. Each of the slides 37has attachedthereto a-gear box 40 (Fig. 2, 3, 9 and 10) containingintermeshing bevel gears 41 and 42 respectively on the arbor 34 and theassociated vertical drive shaft 43. The bevel gears 42-are-splined tothe shafts-43 so as to be freely slidable thereon while receiving rotarymotion therefrom. This permits the arborsv 34 to move vertically so thatthe saws thereon will transversely score-the ice cake while itisstationary within' the frame.

The arbors 34 on opposite sides of the machine are normally located oneat the top and the other at the bottom, as shown in Fig. '6, so thatallofthe sawsare out ofthe path ofthe ice cake while it is beingk fed intothe frame. During the interval when the cake is stationary-and thefeeding bar 7 is being returned to engage another cake, the upper arborY34 is moved downward'and the lower arbor 34 upward so'as to reversetheir positions vertically of the frame. This is accomplished byshifting mechanism of the following construction i Saw shift mechanismThe motor 3 is connected by a chain'drive 44 (Figs. 2 and 3) with atransverse shaft 45 having the bevel gear wheels 46 and 47 adjacent tothe opposite ends thereof and meshing with bevelgear wheels 48up0n thevertically extending'shafts 43, thereby transmitting the rotary drive tothe arbors 34.

down gear train including they gears 49, 50, 5l and 52 (Figs. 1, 2 and3)'l to a sprocket 53 which drives a chain 54. ThisV chain passes aroundidler sprockets 55 (Fig. l) which are so positioned as to form twoparallel vertical portions of the lchain 54a and The shaft 45 is alsoconnected by a step-Y and 54b with laterally .extending portions 54c and54d at opposite ends thereof. 56 is a. slide engaging a verticallyextending guide rod 57 and having the laterallyextending bifurcated lugs58 and 59 for respectively embracing the strandsk 54b and 54a of thechain.Y The chain carries adog 60 adapted to alternatively engage thelugs 58 and 59 to respectively move the slide 56 upward and downwardupon the guide 57. After each of said movements the dog automaticallydisengages from the lug and the interval in which said dog is passingaround the lateral portions 54 and 54d of the chain is equal to theinterval during which the feeding of the ice cake into the frame isaccomplished.

The slide 56 is connected by a laterally extending arm 61 with avertically extending rack bar 62 (Figsf3 and 5) which slides in atubular guideway 63 and engages a pinion 64 on the horizontallyextending shaft '65 journaled in bearings in the upper -part of theframe. Sprockets 66 are mounted upon opposite ends ofthe shaft 65 andactuate chainsV 67 (Figsf6 .and 11') which pass around idler sprockets66, 66bfand 66c to form an endless circuit. The latter'sprocket ismounted on a4 shaft 65EL parallel to the shaft and upon the oppositeside of the frame. slides 37, 38,A and thefarran'gement is such Vthatwhenever the slide 56 is actuated, one 'of the arbors 34 is moved upwardand the other one downward and in alternative movements of theslide 56,said arbors are moved in reverse directions.

The arbors 3l are driven through gear trains including the gears 68 atthe upper The chains 67 are Vattached to the e ends of the sha-ftsr43,intermediate gears 69 and the gearsrl'()V on thearbors 31.)The

Thisy will communicatef'a continir ous- .movement tosaid chain lO', which,

through the dog 13 and bearings I4 and l5,

impart ai -reciprocatory movement to the slide 7. This Vreciprozcationof the: slide alternately-projects the same outward beyond fthe frame1vand beneath anice cake-on the plat- :fnnmand then returns itto aposition within the frame. Inv the outward movement thedngQcollapseszbythe yielding ofthe spring :.21 sofas' to pass beneaththe ice cake and this collapsingfmovement also lowers the bearing 17'to. be beneath the ice. When the dog passesbeyond theice cake oniv theplatform, .the spring will `restoreit vtovertical. posiztiaon andthe4same movement raises the bearing' 17a-nd lifts the small end-of the icecarl'ze so.v that.' its central axis -is horizontally arranged.. Thus.when lthe slide 7 is moved Einwand, the ice calieis fedpa'st the saws()'which score the opposite sides of the cake centrally andlongitudinally'. Aduring its movement intothe frame. During' this wardmovement the stop"y 26. is Alifted until the *ice caleclearszthesaaneand'then drops into j the' path lof' theI cake.l The forward end of'the-cake strikes the stop 22", which yields by 'the movement of therodQ-Bi and the spring .24.. As 'soonf aslthe'momentum is overcome lthespring'24` will return-the cake while the stop 26 limits'its returnmovement so as to accuratelyposition'it'within the frame.

The feeding movements just described oc curl during the' Vinterval'whenf the d'og 6G' is out of engagement with both of the bifur*catedllu'gs 58 andi 59' so that the slide 56. rel mains stationary;

; Thel'attermove the slides 37 and 88 upon the VertiCalguides 39,thereby moving one-of 'the ment i's` completed the-.slide 7 has againbeen moved? outward toA engage another unscored ice cake and begins its:inward movement. Duringthi's inward. movement'the dog 8 first engagesthe scored ice cake and pushes the same outward'through the 'opening inthe frame 2, the stop-'22l having previously been released by theylatch. 27, while the dog 9 engagesv the unscored cake and feeds itintothe frame.

The operation above described is exceed-v ingly simple as the ice cakesare' not' lifted but are merely' pushed alongv a horizontal way, whichmay be accomplished with eX- penditure of but little energy. Also, thedirection ofl movement is' rectilinear, whichv avoids a great deal ofcomplication. The transverse scoring means is of relatively small' massonly includingthe arbors 34 with their saws, whichare arranged the oneto counterbalance the other. the inertia factor and the energy requiredfor driving' the machine.v Thus a small powered motorv is all that isnecessaryfor the continuous and rapid' operation of the machine.

To divide the large tapering cake into sections of equal volume'the saws35 must be spaced dierentially upon the arbors` 34; also where largecakes of dierent weight are op"- erated upon, a change of the spacing ofthe saws is necessary.. Still further, it is desirable to easily removethe saws when necessary for sharpening or in case of breakage. All ofthese results may be accomplished in the construction shown` in detail.in Figures 17, 17 a and 18, in which 74 and: 75 are clamping collarsarranged on voppositesides of each saw. The collar 74 isadjustablysecured upon the arbor.34 by means of the clamping. key 76. See alsoFig. 4. The saws 35 are formed of semi-circular segments 35a and 35bwhich may be engaged with the arbor from opposite sides thereof withoutthe necessity of removing the arbor from its bearings. Thel sections arethen secured. by tap bolts 77 (Fig. 4)

which pass through registering apertures in the collar 75 and segments35a and 35h and engage threaded apertures 78 in the collar `74.

` 35. n an ice scoring machine, the combination with a hollow frame, ofmeans for intermittently feeding ice cakes through said frame with aninterval of rest for each cake within the frame; verticallyreciprocating scoring means on opposite sides of said frame; meansconnecting said reciprocatory scoring means so that they substantiallycounterbalance each other; each scoring device being adapted to movefrom a position above to a position below an ice cake within the frame,and vice versa; and power-driven mechanisms for actuating said feedingmeans i `and said scoring means.

36. In an ice scoringl machine, the combination with a hollow frame, ofmeans for intermittently feeding ice cakes through said frame with aninterval of rest for each cake withinthe frame; vertically reciprocatoryscoring means on opposite sides of said frame.; means connecting saidreciprocatory scoring means so that they substantially Vcounterbalanceeach other; each scoring device being adapted to move from a positionabove to a position below an ice cake within the frame, and vice versa;substantially horizontal scoring means on opposite sides of framebetween which the ice cake passes when moved by said feeding means, andwhich score the ice cake on opposite sides substantially at right anglesto the scores made by the vertically reciprocatory scoring means; andpower-driven mechanisms for actuating said feeding means and saidscoring means. In testimony whereof I affix my signature.
